CLEANING DEVICE FOR TEN'IER CHAINS.

Application filed February 7, 1924, Serial No. 691,259, and in Germany April 17,1923.

The cleansing of the chains of endless chain stretching, tentering and drying machines'for fabrics is an operation consuming much time and labour, and s for this reason frequently dispensed with, with the result that the fabric treated is soiled and deteriorated.

The object of this invention is to provide an apparatus which automatically, easily,

uickly, conveniently and thoroughly cleans t ejoints of the chains, the cleansing agent being used economically and without deleterious effect on the fabric.

The improvement consists in providing means for removing from the stretching chains the dirt particles accumulated there'- upon in the course of working. The apparatus consists of feed and distributing devices, arranged on the stretching chain guide, for supplying a suitable cleansing agent such as steam, air, gas mixtures or liquid under pressure to any number of the stretching chain only when the parts of the chain to be cleansed are facing the outlet orifices.

An example is illustrated in the annexed drawings, in which Fig. 1 illustrates the course of the stretching chain in a multi-sta e stretching machine and the relation of t e cleaning device thereto,

Fig. 2 is a vertical section of the cleaning device and a portion of the chain,

Fig. 3 is a side view of the cleaning device itself, and

Fi 4 is a top plan view of a portion of the c ain, partly in section.

D designates the chain; the fabric to be fed to a is'wound off the roll A, and the fabric is folded into a pile at B when it leaves the chain.

Frequently hot air is introduced into the divisions I, II and III and the pressure of this air is liable to detach dirt from the stretching chains and carry it into the fabric, which becomes soiled. At 0 is the device for cleansing the chain.

The cavities a, 12 indicated by oblique shading at the joints of the chain, are the parts where dirt accumulates and is difficult to remove- Above the chain the cleansing appliance is arranged. It comp'risesa box 1, containing a distributing valve 2, which has ports a, d, 0 whereby the cleansing agent fed to the casing through theinlet f is allowed at intervals to enter the valve, whence it flows through ports 9 and k to the parts a and b. As indicated in Fig. 2 the inlet f is in connection with a steam pipe although it is obvious thatany other suitable agent may be employed. The chain guide has a gap through which the detached dirt falls into a receptacle '3.

If some solvent of dirt is to be added to the cleansing agent, this can be easily supplliedfwith the cleansing agent through the in ct The distributing valve 2 may be rotated by means of the sprocket wheel 4 engaging the chain, and two spur wheels 5 and 6, the wheel 5 being fixed to the wheel 4.

What I claim is:

1. Means for cleaning a tenter chain, comprising a dispensing device for a cleansing fluid, a discharge outlet for said dispensing device terminating adjacent the chain, and mechanical means for operating said dispensing device as each joint of the chain comes opposite the terminus of said discharge outlet.

2..Means for cleaning a tenter chain, comprising a dispensing device for a cleansing fluid, a discharge outlet for said disp'ensing device terminating adjacent the chain, and means driven by the chain during its travel for operating said dispensing device as each joint of the chain comes opposite the terminus of said discharge outlet.

'3. Means for cleaning a tenter chain, comprising a supply of cleansing fluid, a dis charge outlet' for said supply terminating adjacent the chain, valve means for controlling said outlet, and means for actuating said valve means to open said outlet as each joint'of the chain comes opposite the terminus thereof.

4. Means for cleaning a tenter chain, comprising a container for a cleansing fluid, a discharge outlet for said container terminating above the chain, a receptacle below the chain opposite said outlet, valve means for controlling said outlet, and means for actuating said valve means to open said outlet as each joint of the chain comes opposite the terminus thereof.

5 Means for cleaning a tenter chain, comprising a supply of cleansing fluid a discharge outlet for said supply terminating adjacent the chain, valve means for controlling said outlet, and means operated by the chain for actuating said valve means to open said outlet as each joint of the chain comes opposite the terminus thereof.

6. Means for cleaning a tenter chain, comrising a fluid. pressure supply, an outlet or said fluid pressure supply terminating adjacent the chain, and mechanically operated means for releasing said fluid through said outlet as each joint of the chain comes opposite the terminus thereof.

7. Means for cleaning a tenter chain, comprising a fluid pressure supply, an outlet for said fluid pressure supply terminating adjacent the chain, and means controlled by the chain in its travel for releasing said fluid through said outlet as each joint of the chain comes opposite the terminus thereof.

8. Means for cleaning a tenter chain, comprising a fluid pressure supply, an outlet for said fluid pressure supply terminating adj acent the chain, a re'voluble member driven The foregoing s ecification si ed at Dresden, Germany, t 's 19th day 0 Decem- 25 her, 1923.
